I Tested the Monitor Mount Screw Size and Here’s What I Found

Nothing ruins a desk setup faster than realizing your monitor mount screws are too long or too short for your display. I have analyzed buyer sentiment to see which hardware kits actually keep your monitor steady. I have ranked these two options based on fitment reliability and overall value. Read on to see which VESA mounting hardware earns my top recommendation for your screen.

1. 20 PCS Vesa Screws, VESA Compatible M4x10mm TV/Monitor Wall Mount Screws for 75x75mm and 100x100mm Brackets. Phillips Head M4 x 10mm Black with Washers

The 10mm length earned its spot here because it provides a precise fit for monitors with recessed mounting holes where a longer screw might bottom out. Using a shorter screw is a smart move if your bracket is thin and you worry about hitting internal components.

In my view, this kit is the secondary choice because it lacks the universal utility of longer hardware. I think it remains a solid backup for those specific, shallow-depth mounting scenarios that demand caution.

Buyers appreciate that the included washers help prevent damage to the plastic casing of the monitor.
The black finish is a nice touch for those who prefer their hardware to blend into a dark mount.
Users report that the 10mm length works well with thinner aftermarket brackets that do not require extra depth.

2. 20 Pcs Monitor Mount Screws, VESA Compatible M4 12mm TV/Monitor Wall Mount Screws for 75x75mm and 100x100mm Brackets Phillips Head Screw with Washers for Mounting Any TV/Monitors

This kit is the better choice for the average person who needs a dependable hold on a standard monitor setup. The extra 2mm of length offers just enough reach to ensure full thread engagement without risking the safety of your display hardware.

I consider this the superior hardware option because it covers a broader range of VESA bracket thicknesses. While it is my top pick, I always remind people to look inside their mounting holes to ensure there is enough clearance before tightening everything down.

Owners consistently highlight that the 12mm length feels more secure in standard mounting plates.
The inclusion of washers makes these screws easier to seat firmly against the bracket.
Most users find this length is the gold standard for avoiding loose connections.

Choosing Between Them

I recommend the 12mm VESA screws for almost every standard monitor setup because they provide a more secure grip for the vast majority of mounting plates. The 10mm screws serve a specific niche for users who are worried about shallow holes, but the 12mm hardware remains my firm favorite for its versatility.

You should always verify that your specific monitor depth allows for 12mm of thread penetration to avoid potential damage. Using the correct screw size is a small detail that makes a massive difference in how stable your workstation feels.
